Comfort Temperature and Lighting Intensity: Ergonomics of Laboratory Room Machine Tools

Abstract

Laboratories that meet ergonomic standards will support the learning process, both academically and technically, to facilitate the growth and development of skills. This study aims to uncover and provide an overview and information about laboratory ergonomics standards which include thermal comfort (temperature), workspace laboratory lighting. This study uses a quantitative approach with a survey method carried out in the Machine Tool Unit Laboratory of the Department of Mechanical Engineering Education with a population of 60 students who are carrying out practicum. Techniques using direct observation and measurement. Lux Meter to measure lighting and then Digital Thermometer which functions to measure temperature at the observation point in the laboratory. Data collection starting at 07.00 until 12.00 and in the afternoon starting from 13.00 to 16.00, which is the time to do work activities. Measurements made at ten observation points the results showed that; (1) thermal comfort (temperature) with a value of 30.44 degrees Celsius, while the ideal practical standard ranges from 24 – 27 degrees Celsius; (2) Lighting with a value of 422.14 Lux while the ideal practice standard ranges from 500 – 1000 Lux. These results indicate that there is a tendency for temperature and lighting in laboratory rooms under conditions that are less than the standard set. To increase work productivity, these factors can cause less concentration and stress at work.

The Impact of Sensory Stimuli on Healthcare Workers and Outcomes in Trauma Rooms: A Focus Group Study

“…The influence of temperature on staff physical and mental work performance varies based on the nature of the work environment and tasks (Idkhan & Baharuddin, 2019). In the trauma room, proper temperature should be prioritized for patient comfort and then staff comfort, both of which can have implications for patient safety in the form of hypothermia or staff task disruption.…”

“…Proper lighting provides an improved and invigorating atmosphere to minimize work exhaustion and improve productivity (Idkhan & Baharuddin, 2019).…”

“…Providing patients with lighting control in patient rooms reduces cognitive demands on nursing staff, reduces disruptions, and increases patient satisfaction (Lavender et al, 2020). Proper lighting provides an improved and invigorating atmosphere to minimize work exhaustion and improve productivity (Idkhan & Baharuddin, 2019).…”

Evaluation of weaving craftsmen stations on lighting based on ergonomic principles

“…Most workstations need additional lighting so that workers can do their work optimally. The tendency for lighting to be less than the standard set can impact a lack of concentration and stress at work [4].…”

Comparative Analysis of Indoor Environmental Quality and Self-Reported Productivity in Intelligent and Traditional Buildings

“…Aflaki et al [15] assessed the indoor environment in a traditional library building and indicated poor lighting conditions-with the light intensity in the reading zone found to be below 300 lux. Idkhan and Baharuddin [37] conducted a study on sixty students in the laboratory of a traditional university building in Indonesia. The average light intensity amounted to 422.14 lux, which was below the national standard requirement.…”
